Abstract
The dynamic response characteristics of an electro-hydraulic (EH) physical plant is represented by a model. The model includes a series of second order transfer functions, one for each operating point, of the EH physical plant. Command pressure, overshoot, rise time, damping coefficient, natural frequency and gain parameters are determined in developing each transfer function. The model can be used to advance the time in which the design and development of a control system for the EH physical plant can begin.
